To Oppose Any Foe is a compilation of essays on the historical, legal, and contemporary legacy of the Vietnam War that challenges much of the conventional wisdom surrounding that watershed conflict. The book addresses the aftershocks and consequences of America’s ill-fated intervention in Vietnam, from the Cambodian killing fields to nation-building in Somalia to evolving legal thinking on war crimes. The last U.S. helicopter left Saigon over three decades ago, but the Vietnam War still haunts the American memory. It lingers as one of America’s most stinging foreign policy failures, prompting numerous attempts to draw lessons from the experience. These essays demonstrate that the idealism underlying the Vietnam War, which was trumpeted by President John F. Kennedy’s inaugural pledge to “oppose any foe” of liberty, resonates to this day as America engages in another “long, twilight struggle” against global terrorism in the post-September 11 world.
